No severe complications related to the balloon occlusion procedure were noted in either group. Conclusion IABO and IIABO are safe and effective options for cesarean delivery in patients with combined placenta accreta and placenta previa. The average operation time, balloon occlusion time, and fetal radiation dose in patients with IABO are less than in patients with IIABO. There were no complications related to balloon occlusion of the aorta or internal iliac artery.Purpose This study aimed to retrospectively evaluate the safety and efficacy of ureteral stent placement using the rendezvous technique for the treatment of postoperative ureteral complications in cancer patients. Materials and methods From January 2005 to April 2015, 19 patients (2 men and 17 women; median age, 59; range, 42-79 years old) with unilateral ureteral lesions (ureteral leakages in 6, strictures in 4, and both in 9) underwent ureteral stent placement using the rendezvous technique. Percutaneous nephrostomy was performed, and stent placement was attempted via antegrade and retrograde approaches. The technical success, procedure-related complications, and clinical success were retrospectively analyzed. Results The median follow-up period was 29.8 months (range, 0.3-116.5 months). The ureteral stent placement was successful in 17 out of 19 patients (89.5%). Double J ureteral stent was used in 6 patients, and straight catheter as an internal-external nephro-ureteral stent was used in 11 patients. The rendezvous technique was used in the retroperitoneal space and urinary tract in 6 and 11 patients, respectively. No major complications related to the rendezvous technique occurred. Finally, 4 patients achieved stent-free condition (21.1%), and periodic stent exchange was continued in 9 (47.4%). However, permanent external drainage and surgical reconstruction were needed in 4 (21.1%) and 2 (10.5%) patients, respectively. The final clinical success rate was 68.4% (13 out of 19 patients). Conclusion Ureteral stent placement using the rendezvous technique for the treatment of postoperative ureteral complications in cancer patients is safe and may be alternative to permanent external drainage and invasive surgical reconstruction. Level of evidence Level 4, Case series.Purpose To identify risk factors for local and distant intrahepatic tumor progression after percutaneous ablation of HCC and to compare MWA with monopolar RFA. Materials and methods Consecutive patients with early or very early HCC who underwent percutaneous monopolar RFA or MWA were included. Factors associated with local and distant tumor progression were identified. Propensity score matching (PSM) was used to limit bias. Statistical analyses were performed with the Kaplan-Meier method using the log-rank test and Cox regression models. Results One hundred ninety HCC (mean diameter 23 ± 8.6 mm) were treated by RFA (n = 90, 47%) or MWA (n = 100, 53%) in 152 patients (mean age 63 ± 11, 79% men) between 2009 and 2016. The technical success rate was 97.4% (n = 185 HCC). After a median follow-up of 24.6 months (IQR 9.7-37.2), 43 (23%), HCC showed local tumor progression [after a median of 13.4 months (IQR 5.8-24.3)] and 91 (63%) patients had distant intrahepatic tumor progression (after a median of 10.4 months (IQR 5.7-22). The cox model after PSM identified treatment by RFA (HR, 2.89; P = 0.005), HCC size ? 30 mm (HR, 3.12; P = 0.007) and vascular contact (HR, 3.43; P = 0.005) as risk factors for local progression. Factors associated with distant intrahepatic progression were HCC ? 30 mm (HR, 1.94; P = 0.013), serum AFP &gt; 100 ng/mL (HR, 2.56; p = 0.002), and hepatitis B carrier (HR, 0.51; p = 0.047). Conclusion The rate of local HCC progression was lower after MWA than monopolar RFA, regardless of tumor size and vascular contact. The ablation technique did not influence the risk of distant intrahepatic tumor progression.In this study, we accessed culturable fungal assemblages present in the sediments of three lakes potentially impacted anthropogenically in the Fildes Peninsula, King George Island, Antarctica and identified 63 taxa. https://www.selleckchem.com/products/epoxomicin-bu-4061t.html Cladosporium sp. 2, Pseudeurotium hygrophilum, and Pseudogymnoascus verrucosus were recovered from the sampled sediments of all lakes. High concentrations of metals and the lowest fungal diversity indices were detected in the sediments of the Central Lake, which can be influenced by human activities due to their proximity to research stations to those of the other two lakes, which were far from the Antarctic stations. At least one type of biological activity was demonstrated by 40 fungal extracts. Among these, P. hygrophilum, P. verrucosus, Penicillium glabrum, and Penicillium solitum demonstrated strong trypanocidal, herbicidal, and antifungal activities. Our results suggest that an increase of the anthropogenic activities in the region might have affected the microbial diversity and composition. In addition, the fungal diversity in these lakes may be a useful model to study the effect of anthropogenic activities in Antarctica. We isolated a diverse group of fungal taxa from Antarctic lake sediments, which have the potential to produce novel compounds for the both the medical and agriculture sectors.Cultivation and molecular approaches were used to study methanogenesis in saline aquatic system of the Lake Elton (southern Russia), the largest hypersaline lake in Europe. The potential rates of hydrogenotrophic, acetoclastic, methylotrophic and methyl-reducing methanogenesis and diversity of the growth-enriched for by adding electron donors methanogenic communities were studied in the sediment slurry incubations at salinity range from 7 to 275 g/L. The most active pathway detected at all salinities was methylotrophic with a dominance of Methanohalobium and Methanohalophilus genera, at salt saturation and moderately halophilic Methanolobus and Methanococcoides at lower salinity. The absence of methane production from acetate, formate and H2/CO2 under hypersaline conditions was most probably associated with the energy constraints. The contribution of hydrogenotrophic, acetoclastic, and methyl-reducing methanogens to the community increases with a decrease in salinity. Temperature might play an important regulatory function in hypersaline habitats; i.
